🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the front turn signal lamp housing

• Go to the front corner of the fender flare where the amber lens is.
• Use a trim removal tool to gently pry at the rear edge of the lamp housing.
• Pull the lamp housing straight out to release the retaining clips.
• Work slowly to avoid breaking the tabs.

Step 2: Remove the bulb socket

• With the housing loose, locate the bulb socket on the back of the lamp.
• Twist the socket counterclockwise using your hand (or help it gently with a small flat-blade screwdriver if it’s tight).
• Pull the socket straight out of the lamp housing.

Step 3: Replace the bulb

• Pull the old bulb straight out of the socket while wearing nitrile gloves.
• Push the new 3157A/3157NA amber bulb straight into the socket until fully seated.
• Apply a tiny amount of dielectric grease to the socket seal if available (this helps keep moisture out).

Step 4: Reinstall the socket and housing

• Insert the socket back into the lamp housing.
• Twist clockwise by hand until it locks in place.
• Line up the housing tabs with the fender flare and push firmly until the clips snap back in.

Step 5: Repeat on the other side

• Repeat Steps 1–4 on the other front corner.
• Replace bulbs in pairs for even brightness.

✅ After Repair
